Bhikkhus, if you develop and make much this one thing, it invariably leads to weariness, cessation, appeasement, realization and extinction. What is it? It is recollecting the Enlightened One.

He who knows only his own side of the case knows little of that. His reasons may be good, and no one may have been able to refute them. But if he is equally unable to refute the reasons on the opposite side, if he does not so much as know what they are, he has no ground for preferring either opinion … ...He must be able to hear them from persons who actually believe them … he must know them in their most plausible and persuasive form.John Stuart Mill

I cannot help but get annoyed at things like this... it's just a website. Back when the internet as the reserve of nerds, we learnt how to use it responsibly. We grew a thick skin and avoided the online dangers. Normal people viewed the internet as the domain of nerds. Since Facebook came along, absolutely everyone is online, updating their statuses whilst sitting in the toilet, interacting with their real life friends via this new medium. Unlike the nerds, these normal people don't seem to realise that it is just a website, and they don't have to use it.
